Myinvention relates to a ventilator and a; has particular reference to a type of ventilator which is adapted for use at the'ridge ofa skylight, whether the skylight is used as an entire roof of a building, such as a garage or the like, or whether it is used as a unit for admitting light through the roof of a larger building.

Another and further object of my inven 19 tion is the provision of a ventilator which y is capable of being adjusted to varying pOS1' tions so that an adequate change of air can be secured in a building without the creation of unnecessary drafts or the admission of v outside air in the form of drafts and the like Another and further Object of mymven tion is the provision of a ventilatorv which is especially constructed to allow the air in a building or roof portion of the buildlng to pass out of the building without admitting i the roof will pass out and be replaced by air below the roofportion so that a constant change of air is effected in the building without drafts. x

Another and further object of my 'invention is the provision of a skylight ventilator in which it is not necessary to move any .por-' tion of the glass forming the skylights, such as is common in the ordinary skylights now in present use and therefore mechanical devices for the lifting of these glass panelsis not necessary.

, Ref'erringnow specifically to the Figure/l 'is' atransverse sectional view'on tolike'parts throughout,"a curb 1O isshown which may be of any desired form, and is adapted to rest upon'the tops of the walls of a building adapted tohave roof portions of glassy-and corresponds in general to the roof purlines in abuilding, or where a skylight is constructeduponthe roof of a'building, the curb 10 is supported by the roof structure itself.

This curb portion as shown is a specially formed structure for skylightconstruction and conslstsof a baseportion 11, a riser 12,

andan upper'portion 13;which is adapted-to 1'eceive the lower edge of thepane ofgglass forming the skylight section. A gutter 14 is formed for the purpose; ofgreceiving con- J drawings ff andjin' which like reference characters refer densation which may collect-on the under-V side of the-skylight panes, holes beingpro- Vided through theriser so that this condensate can run out on the outer portion of thecurb10.'

Pairs of jack bars 15, 15 are provided at each end of the buliding, the outer ends of which are mounted upon the portion 13 of the curb 10,-and rest against a hollow rectangular member designated as a whole as 16. This member 16 has a pair of end walls 17 and18 to which strips 19, 19 are secured in any suitable manner and are turned 'upon theinselvesk-and bowed out at their upper sidesso that'a flange 20 is formed for the purpose of preventing dust, dirt and thelike blowing over the upper edge of the member 17 and'downward into thebuilding. The member 16 has a'pair of sidewalls 21 These and other obiects of my invention and 22 respectively these Walls being bent outward at their lower ends sothat ledges 23, 23 are formed thereon upon which the ends o'f'the bars hereinafter described are adapted to rest. A pair of angles 24,24 are 7 th'eskylight and is blown up against the with the corners of the rectangular ,niember 16. A plurality. of common bars 26, 26 are provided which are mounted upon the curb 10 at their lower ends 'andupon theledges 23 of the side walls 21 and 22 at theirupper V The number of these common "bars" will depend upon the height, weight and span.

Glass'skylight members 27, 27 are provided andwhich are mountedat, their sides upon the diagonally extending-bars heretofore de- 7 scribed, and; whiclrare supportedby the curb attheir lowerportionsand by theove-rhanging ledges 22.and 23' at their-uppenportions. This is the usual :manner; of. rmounting the glassv sections in=skylight frames and-has nothing to do with my. present invention.

long as it conforms to the substantialdimen- :sionsof theamember 16 over: which it is adapted. to fit. A plurality .ofaverticahbars 29, 29 are provided which are secured at their upper ends to the member 28; and :whose lower ends areunountedinguideways 30, 30 which are securedrto bllGylIlIlOl sidesof therside walls '21 --.and. -.22; :respectivelyu; Extending .,transversely across the member vlfiand secured to the side walls 21 and 22trespectively,

The cap ;28 has an annular outwardly projecting'portion 35 extending therearound with a downwardlyprojecting portion 38, 'f the portion 35u-beingsubstantially of the same angle of the projecting portions 20 and .direction and moving the arms 33,533 to a substantially vertical position softhat the cap within which a rotatably mounted shaft 39 is positioned. The bar 32 on its underside has a pair of loops 40, 40 secured thereto towhich one end of chains 41 and 42 respectively are secured. These loops 40 are spaced a considerable distance from the rotatably mounted shaft 39 which serve the purposeof a pulley over which the chains 41 and; 42 may travel. The purpose of the chains 41 and 42 is to enable a workman to raise or lower the ca 'a 28 as maybe desired, to insure sufficient ventilation in the building. As shown,

when the chain 41 is pulled the bar 32 is moved in a. horizontal direction to the left to assume an angular position. and:lowering' the cap 28 onto-the member 16. When 1t is -.desir-ed to raise the, cap :16, the'.lchain.42= is pulled, thus moving. the bar .32.. in opposite 28 is. lifted, thereby allowing air,;vapors and the like to pass through the member16and outrof thebuilding.

t will thus, be understood thatlthe device while practical. ;for skylight construction,

may be insertedfinany. roof construction where the. rectangular, member is placedin the-roofin placeof the usual ridge pole and .th e ventilating cap secured thereto -in.suc'h- .manner that, it:may be raised or lowered to secure proper fven-tilation depending upon :weather conditions.

H The device will remain in a wide open position orv in any intermediate. position, be tween a wide open and a closed positiori',due to the'friction of the side m'embersin the loops secured to the member-16, and'alsoto the friction of the bar 32 in the members 31 so that it'is unnecessary to provide any fastening means for chains 41 and.42.

VVhile Lhave described more or less precisely' the details of construction, I do .not wish to be understood as limiting myself -thereto, as l contemplate changes in form;

and the proportion of parts and the substitution ofequivalents as circumstances may suggest or render expedient without departing from the spirit or scope of my' invention.
